Jane Austen's House Museum in southern England said it had raised 157,740 pounds ($252,436) — enough to keep the ring in Britain. The funds were raised in just over a month, and included a 100,000 pound donation from an anonymous benefactor.

The "Pride and Prejudice," author died at age 41 in 1817, and left the ring to her sister Cassandra. It had been in the family until the auction last year.

The British government has the power to temporarily halt the export of works judged to be national treasures.

Clarkson — an Austen fan who owns a first edition of the author's novel "Persuasion" — has agreed to sell the ring to the museum.

"The ring is a beautiful national treasure and I am happy to know that so many Jane Austen fans will get to see it at Jane Austen's House Museum," she said.
